You missed the comment "NB. The spike at 2750RPM is caused by the car being released after being held under load on the dyno. It is not present while driving the car on the road."

However I've seen some low-RPM jagged curves from tuners (e.g. COBB Beta tune is pretty non-linear down low). Good to see this not being the case here.

RRP on the rear bolt on section will be $1606. We will have some intro discounts running for the first batch of 20. We are carrying out another dyno test on Tuesday to verify the results of the exhaust on a stock car and will do a detailed post with further information.
